I must be the only one who is bashing this book
I've been really upset with it, because I had to spend a lot of time referring to the specs to check that the information provided in it were correct. It says that it is aimed for SCWCD 1.4, but the TLDs, DTDs... were not updated. It's very confusing, and you'll have to print out diagrams from the spec. Check the author's forum, and you'll understand what I mean.

It's the only one I've been disappointed with. The first version (SCWCD 1.3) was highly praised, but the second one (SCWCD 1.4) is a disaster.
